Abstract: A data queueing apparatus processes data switching and queueing using a smaller capacity memory, while reducing data discard and loss possibility. Received limited-length data at the input line is written in shift memories, which can shift the data to the next stage regardless of the destination of the data. Destination indicating bits, which indicate the destination of the data, are associated with each of shift memories. A search circuit detects an asserted bit among the destination indicating bits corresponding to the output lines. The data is extracted by a selector. Then the selector transmits the data to the desired output line, and the data stored in the previous stage of the shift memory is shifted.      The memory is used in common with a plurality of output lines, so that a lower possibility of data discard and loss can be attained in a smaller capacity memory.

Title: Method and apparatus for transferring a radiotelephone call from one coverage area to another
Inventor: LODWIG JOHN P
IPC: H04B7/26
Filed: 1994-06-08
Abstract: Handoff between coverage areas is achieved in a radiotelephone system coupled to standard wireline switches. Upon initiation of a radiotelephone call in one radio coverage area, a directory number and radio call identifier (203) are downloaded to the subscriber unit (101) from a fixed control unit (111) associated with the coverage area. When the subscriber unit determines a handoff to a target radio coverage area is desirable, it transmits the directory number and radio call identifier to another fixed control unit (113) associated with the target radio coverage area. This fixed control unit calls the directory number and is coupled to the first fixed control unit via the standard wireline switch (115, 117). The radio call identifier is then sent to the first fixed control unit to enable the proper connection for handoff.

Patent CA-2154540-A1 (CA)
Inventor: WOOD JAMES A
IPC: B60T8/58
Filed: 1995-07-24
Abstract: This invention provides method and apparatus for an improved pattern recognition wheel slide protection system for passenger transit  type  railway  vehicles.    It  receives  as  inputs  the rotational velocities of all the axles on the vehicle, and the acceleration rates for the axles.  It also receives signals for brake  cylinder  pressure.    The  system uses  the  velocity  and acceleration data to determine whether the wheels on an axle are slipping, and determines the severity of the slip.  It calculates a timeout value based on the severity of the slip, and times a slip correction until the timeout value is reached, whereupon the slip correction is terminated. The system uses a simplified logic for providing brake control signals.  A cascade logic method is used in which  the  brake  control  signal  starts  out  indicating  full application, then, based on signals indicating change in sign of acceleration  rate,  and  acceleration  rate  in  excess  of  a predetermined value, changes the brake control signal to pulsed brake application.  Further indications based on axle velocity and acceleration cause the signal to change to a hold signal, then to a release pulse signal, and finally to a signal for release.  This cascaded logic provides signals for brake valve control which have five values, APPLY, APPLY PULSE, HOLD, RELEASE PULSE, and RELEASE. Information obtained from axle rate signals is also used to specify for the RELEASE PULSE mode the duration of release and the duration of hold.
